Sargent 10-3158 26D – Frequently Asked Questions

1) What exactly is the Sargent 10-3158 - is it a complete lockset or just the lock case?
It's the lock body only, the mechanical case that houses the lock works. Trim, levers or knobs, and the cylinder are not part of it. Sargent supplies the 10-3158 as an OEM replacement part for service work on compatible Sargent lock assemblies, so you reuse the existing trim and core unless those are also worn.
2) Will the Sargent 10-3158 lock body accept a Schlage interchangeable core?
Yes, it comes factory prepped for Schlage Full-Size Interchangeable Core (FSIC) cylinders. That means a facility already keyed on Schlage FSIC can drop its existing core straight in and keep the lock on the same key system. It is not prepped for a small format (SFIC) figure-eight core, and it is not the standard Sargent LFIC prep, so confirm which core your building uses before ordering.
3) What does the SF-10G05 function on this Sargent lock body do?
SF-10G05 is the function the 10-3158 case is built for, and the case is configured mechanically for that function only. A lock body is function-specific, so if the door you are servicing is a different G-function (office, classroom, storeroom and so on), this case will not produce that operation even with the right trim on it. Match the function stamped on the lock you are replacing.
4) I'm replacing a worn Sargent lock - what do I need to check before ordering the 10-3158?
Three things decide it. First, the function: this case is built for SF-10G05 and nothing else. Second, the cylinder prep: it takes a Schlage FSIC core, so if your building runs a different core format the case is wrong for you. Third, whether the failure is actually in the case. If the problem is a loose lever, a broken spindle, or a sticky cylinder, a new lock body will not fix it and you need the trim or cylinder part instead.
5) What finish does the Sargent 10-3158 come in?
One finish: 26D, satin chromium plated over nickel, commonly called satin chrome. On a lock body the finish matters less for looks than for matching a service order, since the case sits inside the door, but if you are standardizing spare parts across a building, 26D is what you will be stocking.
6) Is the Sargent 10-3158 lock case suitable for high-traffic commercial doors?
It's a commercial-grade component, built to Sargent's lock case standards for daily high-use operation, and it is not a residential part. Typical placements are office buildings, schools, hospitals, government facilities, multi-tenant residential, retail, and industrial or warehouse doors.
